The original recipe said to run your microwave on 100% power, but I had to kick mine down a notch to be running at 90% power. I think this recipe was developed with an older microwave in mind. If your microwave is less than about 3 years old I would definitely run it at 90% power.

The nice thing about this recipe is that you can tell when the peanut brittle is done. Your butter and corn syrup mixture will go from being white in color to a golden brown. If you take the bowl out of the microwave when the mixture is a nice light golden brown, it will turn out perfect. Definitely keep a close eye on it!

Butter a cookie sheet. In a large microwavable mixing bowl, stir together sugar and corn syrup. Microwave for 4 minutes.

Stir in the peanuts and salt, and microwave for 3 1/2 minutes.

Mix in the butter and vanilla extract, and stir until butter is melted. Microwave for 1 1/2 minutes.

Remove the bowl from the microwave and stir in the baking soda. Pour the peanut brittle mixture onto the greased baking sheet, spreading slightly with a spatula if necessary. The peanut brittle will flatten as it cools.

Let the peanut brittle cool to room temperature, then break it into pieces.
